\VILLIAM YOULTEN, OF LONDON, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 600,472, dated March 8, 1898.

Application filed November 19, 1897. Serial No. 659,158. (No model.) Patented in England April 26, 1895, No. 8,324, and June 6,1895,N0.11,138.

To all whom, it 'ntay concern:

Be it known that I, WILLIAM YOULTEN, a subject of the Queen of Great Britain and Ireland, residing at 159 Victoria street, IVestminster, London, England, have invented Improvements in Pivoted lVindow Sashes, Doors, and the Like, (for which I have obtained patents in Great Britain, No. 8,324, dated April 26, 1895, and No. 11,138, dated June 6, 1895,) of which the followingis a specification.

According to the first part of my invention I provide in any center-hung window, door, and the like a semicircular socket let in flush with one of the abutting planes of either the frame or revolving sash, door, and the like. On the opposite plane I provide a suitable pivot. From the said semicircular socket a clearway the full width of the pivot is provided to the internal face of the center-hung sash, door, and the like, enabling the latter to be drawn over the pivot previously described. The clearway before mentioned is plugged in any suitable manner, the end of the removable plug or plate being semicircularly hollowed to complete a circular socket around the pivot. By these provisions center-hung windows, doors, andthe like may be readily removed for the execution of repairs, and in the case of reversible sliding sashes swung on cord stiles the employment of the usual inside removable bead is rendered unnecessary.

According to the second part of this invention, in order to provide a simple and efficient weather-check between the faces of the cord and glass stiles in reversible sliding windows and the like I form in each abutting face of the said stiles any suitable number of corrugations or waves, so placed in juxtaposition that when the sash is in its ordinary or vertical position the convex surfaces of the corrugations formed on the abutting faces of the cord stiles enter the concave surfaces of the corrugations formed on the abutting faces of the glass stiles, and vice versa.

By the use of any suitable means of drawing the two stiles together, such as may be effected by the insertion of thumb-screws through the glass stiles, the two stiles will be to describe the same with reference to the drawings accompanying this specification, in which Figure 1 is an elevation of a portion of a pivoted window-sash, showing my improvements adapt-ed thereto. Figs. 3, 1, 5, and 6 are details hereinafter referred to; and Fig. 2 is a section on line A B, Fig. 1, and refers more particularly to the second part of my invention.

The same letters of reference are employed to denote the same parts in all the views.

The window-sash shown in Fig. 1 is divided so as to form two parts a and Z), the surfaces 0 of the part a and cl of the part b abutting. The parts a and b are shown detached at Figs. 3 and 4, respectively, showing the abutting surfaces 0 and d.

6 shows a plate screwed flush with the surface d, such plate being formed of semicircular shape at f.

9 shows a slot or clearway cut in the plate e and portion 5 of the sash.

h shows a plate provided with a pivot i,such plate being screwed flush with the surface 0 of the part a of the sash.

k is a plate formed or provided with a plug Z, this latter having a semicircular slot cut therein, as at m, Fig. 5, which figure shows a detached view of this plate 7.; and plug Z.

n a show screws for connecting the two parts a and I) together.

The plate It is screwed onto the part b of the sash, as shown at Fig. 1,so that the plug Zpasses into the slot or clearway g. The semicircular portion of this plug coming directly over the semicircular part f of the plate 6 forms a hole in which the pivot i works.

Fig. 6 is an end View of plate It and plug Z.

Supposing the window-sash to be in the position shown at Fig. 1, in order to allow the window to turn on its pivots i (of which, of course, there are two, one on each side of the window) it is simply necessary to unscrew the screws n n, and if it is desired to remove the window for cleaning or repairs the plates 70 are taken off, enabling the portion 1) of the sash to be drawn away clear of the pivots i.

The portion a of the sash may be the cordsash stile, so that b may swing thereon.

It will be seen on reference to Fig. 2 that the abutting surface 0 of the part a and the abutting surface (1 of the part b are formed with any suitable number of corrugations or Waves 0; These corrugations -o are so arranged that when the sash is in its ordinary vertical position the convexities of the corrugations formed on the surface 01 enter the concavities of those formed on the surface 0, and vice versa.

12, Fig. 2, shows the throat-groove to prevent the passage of water.

The pivotc' being of suitable length to allow of a play equal to the horizontal width of the corrugations between the sash and the sash-frame, upon releasing the screws 42 or other stile-fastenings the sash can be revolved.

It will be seen that when the parts a and b are drawn tightly together by means of the thumb-screws n n or other fastener an efficient draft-proof joint is obtained, owing to the surfaces 0 and d being corrugated, as before described.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In improvements in pivoted windowsashes, doors and the like, the parts a and 1) provided with pivots and semicircular sockets f, slots or clearways g and plugs Z, all for the purposes set forth.

2. In a pivoted window-sash, door or the like, the combination with two abutting uprights, the one having a slot or clearway formed in its edge, and a pivot-pin fixed upon the edge of the other upright and adapted to engage in said slot or clearway; of a plate having a semicircular incision at one edge mounted over said slot or clearway; and a second plate mounted over the end of said slot or clearway and having a projection of the width of said slot extending thereinto and having a semicircular incision in its end, substantially as described.

M. YOULTEN.
